We investigate the dependence of the strength of galaxy clustering on intrinsic luminosity using the Anglo-Australian two degree field galaxy redshift survey (2dFGRS). The 2dFGRS is over an order of magnitude larger than previous redshift surveys used to address this issue. We measure the projected two-point correlation function of galaxies in a series of volume-limited samples. The projected c...
The accuracy of effective masses predicted by density functional theory depends on the exchange-correlation employed, with nonlocal hybrid functionals giving more accurate results than semilocal functionals. In this article, we benchmark performance Perdew-Burke-Ernzerhof (PBE), Tran-Blaha modified Becke-Johnson (TB-mBJ), and Heyd-Scuseria-Ernzerhof (HSE06) potentials for calculation perturbati...
As a generalization of neutrosophic set, the notion MBJ-neutrosophic sets is introduced by Mohseni Takallo, Borzooei and Jun, it applied to BCK/BCI-algebras. In this article, set used study commutative ideal in BCI-algebras. The concept closed their properties relationships are studied. conditions for an be given. provided. Characterization established. Finally, extension property founded.
The primary goal of this study is to investigate the effect different exchange-correlation functionals on optoelectronic and elastic properties Ag2O chalcogenide compound. For electronic structures optical spectra, Tran-Blaha modified Becke-Johnson approach combined with GGA GGA+U (mBJ-GGA-PBEsol mBJ-GGA-PBEsol+U, respectively) was used. available theoretical experimental data for bandgap energ...
The electronic and optical properties of CdSe in two phases, cubic and wurtzite, have been studied by first principal calculations using the density functional theory. The optical parameters such as transmittance, optical absorption, refractive index and extinction coefficient have been investigated. We have calculated also the band structure, and total/partial density of state using the full p...
We have analysed the optical luminosity-redshift distribution properties of bright QSOs, using a new large sample from the Hamburg/ESO survey. The sample provides insight into the hitherto poorly sampled bright tail of the luminosity function, allowing to monitor its evolution with redshift up to z ≈ 3. The slope increases significantly towards higher z, inconsistent with the predictions of pur...
